- key study
- Study period:
- 2016-05-18
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no

- yes (incl. QA statement)
- Type of method:
- capillary method
- Key result
- Atm. press.:
- ca. 101 325 Pa
- Decomposition:
- yes
- Remarks:
- The substance appeared brown at approx. 300 °C and started to decompose at about 330 °C.
- Decomp. temp.:
- ca. 330 °C
- Conclusions:
- As the substance decomposed at approx. 330 °C, no melting point could be determined.
- Executive summary:
The melting point of the substance was investigated in an experimental study under GLP conditions according to OECD Test Guideline 102 using the capillary method. As the substance decomposed at approx. 330 °C, no melting point could be determined.
Reference
Testing the control substance caffeine (mean melting temperature of 236.1 °C) confirmed the reliability of the apparatus.
Description of key information
As the substance decomposed at approx. 330 °C, no melting point could be determined (reference 4.2-1).
Key value for chemical safety assessment
Additional information
The melting point of the substance was investigated in an experimental study under GLP conditions according to OECD Test Guideline 102 using the capillary method. As the substance decomposed at approx. 330 °C, no melting point could be determined.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
